Preferably, the free end of the pushing rod 82 is provided with a pushing plate perpendicular to the axis of the pushing rod 82, and when the pushing rod 82 extends, the pushing rod 82 abuts against the pushed workpiece 9 through the pushing plate to push the workpiece 9 to the discharge hole 12; the push plate can increase the contact area of the push rod 82 and the pushed workpiece 9, and disperse the extrusion acting force applied to the workpiece 9 by the push rod 82, so that the workpiece 9 can be pushed to the position of the discharge hole 12 more stably, and the problems of deflection, dislocation and the like of the workpiece 9 are reduced.

In the embodiment, the discharge port 12 of the feeding mechanism 1 is located on one side surface of the outer frame 3, the top air cylinder 81 of the pushing mechanism is disposed on the other side surface opposite to the one side surface, the workpiece 9 or the material carried on the substrate 21 is disposed between the discharge port 12 and the top air cylinder 81, so that the piston cylinder of the top air cylinder 81 abuts against the tail end of the workpiece 9 and pushes the whole workpiece 9 to move toward the processing port, the head end of the workpiece 9 moves to the discharge port 12 first, and then the whole workpiece 9 passes through the processing port and moves to the next designated device.

Fig. 4 is a schematic view of a partial structure for automatic material supply and discharge according to an exemplary embodiment of the present invention, and in the illustration, a partial structure at the discharge port 12 is mainly shown.

In the embodiment of the present invention, the feeding mechanism 1 is provided with the first discharging roller 121 and the second discharging roller 122 which are rotatable, and the first discharging roller 121 and the second discharging roller 122 are horizontally arranged in the same vertical plane (i.e. on the above-mentioned one side surface of the outer frame 3), and are sandwiched to form the discharging opening 12.

In this embodiment, the apparatus for automatically feeding and discharging material of the present invention is applicable to loading, unloading and conveying operations of different types of workpieces 9, and in order to enable more stable conveyance of different types of workpieces 9 at the discharge port 12 and reduce occurrence of slip and deflection, the feeding mechanism 1 of the present invention is further provided with a discharge pressure device 13.

In some optional embodiments, when the workpiece 9 is conveyed on the second discharging roller 122, the discharging pressing device 13 may drive the first discharging roller 121 to descend and approach the second discharging roller 122, so that the first discharging roller 121 contacts the workpiece 9 being conveyed to generate a slight pressure, thereby making the conveying of the workpiece 9 more stable and reducing the slip and skew of the workpiece 9.

As shown in fig. 4, the first discharging roller 121 is a discharging roller located above, the second discharging roller 122 is a discharging roller located below, the discharging pressure applying device 13 includes two small telescopic cylinders, the two telescopic cylinders are respectively disposed above two end portions of the discharging port 12, each telescopic cylinder has a telescopic rod capable of telescopic moving downward, free ends of the two telescopic rods are respectively connected with two end portions of the first discharging roller 121 in a driving manner, so that the first discharging roller 121 can be synchronously driven to move up and down on the vertical surface through the telescopic movement of the telescopic rods of the telescopic cylinders in the vertical direction, and the second discharging roller 122 is fixed; specifically, when the telescopic rod extends, the first discharging roller 121 moves towards the second discharging roller 122, and the distance between the first discharging roller and the second discharging roller is reduced; when the telescopic rod is contracted, the second discharging roller 122 moves back to the second discharging roller 122, and the distance between the second discharging roller and the second discharging roller is increased; thus, the width of the discharge port 12 can be adjusted by controlling the extension and retraction of the two telescopic cylinders.

Alternatively, in another embodiment not shown, the discharging pressing device 13 may also be respectively in driving connection with the first discharging roller 121 and the second discharging roller 122, and may drive the first discharging roller 121 and the second discharging roller to move toward or away from each other; here, when the first discharging roller 121 and the second discharging roller 122 move toward each other, the distance between the two is reduced, so as to achieve the effect of reducing the width dimension of the discharging port 12; when the first discharging roller 121 and the second discharging roller 122 run in opposite directions, the distance between the two rollers is increased, so as to achieve the effect of increasing the width dimension of the discharging hole 12.

Specifically, in the above embodiment, the discharging pressure applying device 13 may include two sets of telescopic cylinders, which are respectively used for controlling the lifting movement of the first discharging roller 121 and the lifting movement of the second discharging roller 122, wherein the design form of the telescopic cylinders for controlling the lifting movement of the first discharging roller 121 may refer to the structure and arrangement manner of the telescopic cylinders disclosed in the previous embodiment; similarly, the design form of the telescopic cylinder for controlling the lifting movement of the second discharging cabinet is as follows: two telescopic cylinder set up respectively in the below at the both ends of discharge gate 12, and each telescopic cylinder all has the telescopic link that can move towards the top is flexible, and the free end of two telescopic links is connected with the both ends drive of second discharge roller 122 respectively, and like this, the telescopic link through telescopic cylinder moves in the ascending flexible of vertical side, can drive the lifting movement of second discharge roller 122 on same vertical face in the aforesaid in step.

In the embodiment of the present invention, the first discharging roller 121 and the second discharging roller 122 may be in a rotation form driven by the friction force applied to the roller surface by the workpiece 9 without being mechanically driven, and may also be in a driving form driven by the mechanical driving of the discharging rollers to rotate, and in the embodiment, the feeding mechanism 1 is further provided with the discharging driving device 14, and the discharging driving device 14 is in driving connection with at least one of the first discharging roller 121 and the second discharging roller 122 to drive at least one of the first discharging roller 121 and the second discharging roller 122 to rotate axially.

For example, as shown in fig. 4, the discharging driving device 14 of the present invention is a driving motor, which is disposed at one side of the discharging opening 12 and is directly or indirectly connected to the second discharging roller 122 located below, and when the driving motor is operated, the second discharging roller 122 can be driven to rotate, so that the second discharging roller 122 can drive the workpiece 9 to move toward the discharging side thereof by the frictional force applied to the workpiece 9 by the roller surface thereof.

Of course, in other embodiments, the driving motor may also rotate with the first storage tank and the second discharge roller 122 respectively to drive the first storage tank and the second discharge roller to rotate in opposite rotation directions, so as to drive the workpiece 9 clamped therebetween to move toward the discharge side.

Preferably, the roller bodies of the first discharging roller 121 and the second discharging roller 122 of the present invention are composed of a plurality of roller sections, and each roller section of a single section can generate a proper amount of dislocation and shaking relative to other adjacent roller sections, so as to adapt to the conveying operation of some workpieces 9 with uneven surfaces and improve the range of the types of the workpieces 9 to which the apparatus of the present invention is applied.

In an embodiment, the device for automatic feeding and discharging further includes an overlap prevention mechanism 4, the overlap prevention mechanism 4 is disposed on the feeding side of the discharging port 12, the workpiece 9 pushed by the pushing mechanism is conveyed to the discharging port 12 through the overlap prevention mechanism 4, and the overlap prevention mechanism 4 can serve as a transition path when the workpiece 9 moves from the substrate 21 to the discharging port 12, and can play a role in supporting the workpiece 9, so that the workpiece 9 can enter the discharging port 12 more stably.

As shown in fig. 4 and 5, specifically, the overlap preventing mechanism 4 includes a vertical baffle plate 41 and a flat plate 42 horizontally disposed toward the discharge port 12. Alternatively, the baffle plate 41 may be vertically fixed to the outer frame 3. The height of the upper plate surface of the flat plate 42 is slightly lower than the upper edge of the baffle plate 41, and the upper edge of the baffle plate 41 is approximately flush with the tangent line of the upper roller surface of the second discharging roller 122. In particular, the baffle 41 may serve as a blocking member (as shown in fig. 5) or as a connecting member between the overlap preventing mechanism 4 and the outer frame 3.

When the pushing mechanism pushes two or more workpieces 9 to the baffle 41, the lower plate surface of the workpiece 9 on the top layer is generally controlled to be parallel to the tangent line of the upper roller surface of the second discharging roller 122, so as to achieve the purpose of conveying the workpieces 9 one by one. However, in the actual production control process, an error is inevitably generated, and it is difficult to make the tangent line of the upper roller surface of the second discharge roller 122, the upper edge of the baffle plate 41, and the lower plate surface of the uppermost workpiece on the same horizontal line, as shown in fig. 5. In the actual production process, since the workpieces 9 may be stuck to each other, a situation may occur in which the adjacent workpieces 9 overlap into the discharge port 12 due to the sticking, and the provision of the baffle 41 can effectively prevent this.

As shown in fig. 5, when the height of the top workpiece 9 is slightly higher than the baffle 41, at this time, even if the top surface of the adjacent lower workpiece 9 is already higher than the upper edge of the baffle 41, the lower workpiece 9 is still blocked by the baffle 41 because the workpiece 9 has a certain thickness, and the pushing device can only push the top workpiece 9 into the discharge hole 12, and the situation that the top workpiece 9 and the adjacent workpiece 9 are pushed into the discharge hole 12 in an overlapped manner does not occur, so that the precise conveying of a single workpiece 9 is realized, and the situation that a plurality of workpieces 9 are overlapped into the discharge hole 12 is avoided.

In the embodiment of the present invention, the overlap preventing mechanism 4 further includes a chute table 43 of a seesaw structure provided on the flat plate 42, and a side of the chute table 43 adjacent to the discharge hole 12 is adjustable in an upward tilting angle by a lifting member.

Fig. 6 is a schematic view showing a part of the structure of the automatic loading and unloading apparatus according to an exemplary embodiment of the present invention, in which the structure of the elevating mechanism assembled with the base plate 21 is mainly shown.

In an embodiment, the height positions of the discharge port 12 and the top air cylinder 81 are corresponding and fixed, and after the top air cylinder 81 pushes the workpiece 9 on the substrate 21 to be output from the discharge port 12, the overall height of the plurality of workpieces 9 is inevitably reduced, and when the uppermost workpiece 9 is lower than the height of the discharge port 12, the top air cylinder 81 cannot push the workpiece 9 any more, so that, to achieve continuous conveying of the workpiece 9, the apparatus for automatic feeding and discharging of the present invention further includes a lifting mechanism, and the lifting mechanism can drive the substrate 21 to lift within a set height range, so that the height of the uppermost workpiece 9 stacked on the substrate 21 is aligned with the height of the discharge port 12, and thus, the pushing mechanism can always push the single uppermost workpiece 9 to the discharge port 12.

Specifically, elevating system includes: one or more lead screws 51 vertically arranged on the outer frame 3, the lead screws 51 being positioned on the outer peripheral side of the base plate 21, each lead screw 51 being provided with a thread formed by extending along the longitudinal direction thereof; one or more guide blocks 52 fixed on the base plate 21 and corresponding to the lead screw 51, each guide block 52 having a through hole for forming a threaded socket fit with the corresponding lead screw 51; and the lifting driving device is in driving connection with one or more lead screws 51 so as to drive the lead screws 51 to rotate axially. Therefore, when the lifting driving device operates in the forward rotation mode, the lead screw 51 is driven to rotate axially along the first rotation direction, the height of the lead screw 51 is unchanged, the guide block 52 is forcibly driven to move upwards along the vertical direction, so as to drive the base plate 21 fixedly connected with the guide block 52 to move upwards, therefore, the workpieces 9 stacked on the base plate 21 can move upwards synchronously, and when the uppermost workpiece 9 moves to a position flush with the feed inlet, the pushing mechanism can push the uppermost workpiece 9 to the feed inlet.

Therefore, after a workpiece 9 is pushed to the discharge port 12 and output to a designated device, the substrate 21 is driven to move upward by a set distance by controlling the operation of the lifting driving device of the lifting mechanism, so that the workpiece 9 on the uppermost layer of the substrate 21 can meet the pushing height requirement of the pushing mechanism. The specific upward movement setting distance may be preset according to the actual thickness of the workpiece 9 to be output.

After all the workpieces 9 on the base plate 21 are pushed, the lifting driving device can reversely rotate, the lead screw 51 is driven to axially rotate in a second rotation direction opposite to the first rotation direction, the height of the lead screw 51 is still unchanged, and the guide block 52 is forcibly driven to move downwards in the numerical direction so as to drive the base plate 21 to also move downwards, so that new workpieces 9 or materials can be stacked on the base plate 21 again.

In the embodiment, two ends of the screw 51 are respectively fixed to the upper and lower frame bodies of the outer frame 3, and the lifting driving device is a driving motor, and the driving motor is directly or indirectly connected with the screw 51 in a driving manner.

In an embodiment, for the aforementioned lifting mechanism of the set of the lead screw 51 and the guide block 52, the lifting mechanism further includes: one or more slide bars are vertically arranged on the outer frame 3, the slide bars are positioned on the outer peripheral side of the base plate 21, and the outer surfaces of the slide bars are smooth; one or more sliding blocks fixed on the base plate 21 and corresponding to the sliding rods, wherein each sliding block is provided with a smooth through hole which is matched with the corresponding sliding rod in a sleeved mode. In this embodiment, the sleeve connection between the sliding rod and the smooth through hole can further limit the substrate 21, thereby preventing the substrate 21 from rotating around the screw 51.

In the foregoing embodiment, the material preparation mechanism 2 is moved into or out of the outer frame 3 by a sliding structure, and the specific structure of the sliding structure includes: a slide rail 61 which is provided on the outer frame 3 and is formed to extend in a direction away from the discharge port 12; a plurality of pulleys 62 disposed at the bottom of the base plate 21, and the base plate 21 can be moved into or out of the outer frame 3 by the sliding engagement of the pulleys 62 and the slide rails 61.
